DOUBLE-SEAMING MACHINE.

an automatic, continuous, rotary, 'double' seaming (machine of a simple,efficient and durable construction, by means of which can headsmay bevery rapidly and cheaply double samed upon can bodies and hermeticallytight seams produced. i

The invention consists in connection with a continuously rotatingcarrier turningoii a horizontal axis', and having a plurality ofhorizontally dis osed can vbody receiving pockets intowhic the canbodies may feed by lgravit-y from a chute into the pockets of thecarrier as the carrier rotates continuously, a plurality of airs ofaxially rotatable can holder chucks mounted `on t-he.carrier, one

pair for each pocket of the carrier,` a plurality of sets of'independently movable double seeming rollers-mounted on the car# rier,one set for each pocket of thepcarrier, stationary cams andconnectioiisffo'r automatically operating the several sets of doubleseamlngollerjs as the carrier rotates continuously, a stationary cam andconnections for reciprocating one fof the rotatable can holder chucks ofeachlpair'as the carrier rotates continuously, and means for axiallyrotating .the rotatable can holder chucks as the carrier revolves.

'lhe invention further consists in thel novel constructionof parts `anddevices and -v in the novel c binat-ions of arts and devices herein sh,wn and descri -d and more particularly specified in the claims.

gether before being fed Vto the machine in cases where it is not desiredto feed the heads and bodies separately tol the machine or to employ oruse a can head chute separate from the can body chute.

In the drawing, 1 represents the frame of the machine, the same being ofany suitable` construction to give support to the other parts.

2 is a continuously rotating carrier, turning on a horizontal axis orshaft 3 and haying a plurality of horizontally disposed can bodyreceiving pockets-1, preferably sxin number. The carrier 2, forconvenience of construction` preferably comprises four separate disks orheads 5, 5 and 6, 6, thetwo inner ones 5, 5 having 'formed therein thecan body receiving pockets l, and the two outer ones 6, 6 carrying thecan holder chucks and seaming roller mechanism.

A plurality of pairs of axially rotatable can holder chucks 7, 8 are.mounted on the,

carrier 2,. one pair for each can body re- One of the eeiving pocket ofthe carrier.

Vcan holder chucks 7 of each pair has a spindle or shaft furnished witha gear 10, which meshes witlra main or central gear 11 to axially.rotate the can holder chucks and the'can clamped between them as thecarrier 2 rotates. The shaftorV spindle 12 of the other chuck 8 of eachpair has a rotatable connection, preferably a ball bearing connection 13eomprisingballs and a ball race, with an adjustable member 14l of'areciprocating Vstem 14 which is( furnished with an anti-friction roller15, engaging a stationary cam 16 on the frame of the machine by whichthe can holder chuck 8 is reciprocated as the carrier 2 revolves toclamp the can between itself and the opposingchuck 7. A spring 17 ispreferably interposed between the can holder chuck 8 and vitsreciprocatin stem 14 of .stem 14 to accommodate variations in length ofthe can bodies 'and give a yielding clamping Vact-ion An adjust-.

to the can holder chucks 7,-8. ing screwv 18 is also preferablyinterposed between the can holder chuck 8 and its reciprocating .stem 14for adjusting the can clam ing `1u0vement of the reciprocati chuck) 8. Aspring 19 acting againstv a p 20, carried by an'ar'm .21 on the stem 14is preferably employed to open thel chuck 8 asy the carrier revolvesinto position to re chute 22.

rllhe cont-lnuouslv rotatine carrier 2 is rovided with a plurality ofsetsof'movable double seaming rollers 23, 2e, one set for each can bodypocket lof the *carrier 2. One of the double seeming rollers 23 of earchset serves to turn, or fold the flange 25 of the can head 26 over theflange 2? of the can body 28, and the other searning;- roller 24 lservesto finishl the seaming operation or compress the folds of the seamclosely and tightly together.

The movable'seaming rollers 23, 2e of' each pair are each mounted uponan vindependently movable tool holder 29. prefer,- ably a vibrating,`arm on roch. shariJ 30, and having` an adjustable connection 3l with therock shaft arm 32, the rock shaft being provided With a further arm 33,carrying an anti-friction roller 3e which. engages stationary cams 85and 36, one cam being employed for operating the forming rollers 23 andthe other for operating the nishing rollers 24.-. The stationary cams35, 36 are preferably on a stationery hub 37, secured to the frame ofthemachine and spi 'i 37 are preferably used to retain the rollers Bil inengagement with the cams 35, 3G.

The shaft 3 of the carrier 2 is preferably continuously rotated from themain driving shaft 38, l :wing fast and loose pulleys 39, 40, through.Athe intermeshing gears lil, 48 and 44, the gears 4-2, 43 being on theintermediate shaft e5.- The main or central gear l1 by which the canholder chucks are axially rotated as the carrier 2 revolves, is

preferably a driven gear instead of a stationary one, and is preferablydriven by a gear 4:6 on the shaft 45,"ineshing` with a gear 47 on thehub 4:8 of the gear ll.

, The can body feed chute 211 is preferablyarranged substantiallyupright so that the can bodies will readily feed down it by gravity, andit is preferably provided with,

i a vibrating feeder or dog 49 to cause the inclination, so .that thecan heads may feed down Lhefsame by gravity against tie can headregistering pins or stops 52 with Which the carrier 2 is provided tocause each can head to properly register with its can body before 'thecan holder chucks 7, 8 close upon the same to clamp the can head on thecanv body preparatory to the seainingy operation. YThe can head feedchute 22l is preferably furnished with a vibrating can head feeder orfinger having an arm 5d operated by a cani or projection 55 on thecarrier 2 as the carrier rotates, and thereby releasing the lowermostcan head in the can. head chute. rlhe length of the contacting face 54aof arm tel is such that the feed linger 53 is only Withdrawn long enoughfrom the path of the can heads in the chute 22 to permit the release ofbut a single can head at a time, a spring 54;"l operating to restore thefeed finger 53 to normal position e soon as the projection 55 passes thecontacting face 5e* After the can head has been seemed upon the can bodyby the'operation of the machine, the :finished can is ejected ordeliyered from the machine intothe discharge chute 56 by the egectordevice 57 which projects into the path of the can bodies on thel carrier2. f

In practicing the invention, it is preferred to feed the can bodies andcan heads separately to themachine and to employ tliio chutes for thispurpose, one for the can bodies and the other for the can heads. lf,however, the heads and bodies are irstassembled together and the flange25 of the 'can head crimped or clenched at two or vmore points ofits'circumference, as at 58, about 95 `the Hangs of the can body, theassembled can heads and can bodies may be together fed to thel machinethrough the can body chute 211, vand in such case, the can head chut-e22 need not be used or may be entirely omitted from the machine ifdesired.
